SPECIFICATION forming part of Letters Patent No. 369,255, da ed August80, 1887.

Application filed Apr-i129, 1886.

To (LZZ whom it may concern:

Be it known that I, J OHN FIARHOEFFER, of the city, county, and State ofNew York, have invented certain new and useful Improvements inQuiltinghiachincs, of which the following is a specification.

This invention relates to certain new and useful improvementsin thatclass of machines used for quilting or sewing a number of lay- IO ers offabric, or fabric and cotton batting, to-

gether, said machines being provided with anumber of needles working atthe same time.

The object of my invention is to simplify the construction of themachine and facilitate the adjustment of the parts as required by thesize, shrinkage, &c., of the fabric.

The invention consists in the combination, with a reciprocating needlecarrier and shuttle guide and carrier, of a cam for operating said partsand shuttle-carrier, an automatic feed mechanism, &c., and in theconstruction and numerous combinations of parts and details, as will befully described and set forth hereinafter, and pointed out in theclaims.

Similar letters of reference indicate corresponding parts.

The entire working parts of the machineare supported by the frameA,which has suitable legs. In brackets of the frame a driving shaft', A,is journaled, provided with a belt-pulley, A and from said shaft theother parts of the machine are operated.

On one end of the shaft A a disk or wheel, B, is mounted, which isprovided with a wristpin connected by a connecting-rod, B, with an arm,13*, on one end of a rock-shaft, B journaled in suitable bearings in thebottom ofthe frame A, said rock-shaft being provided at each end with anarm, B", connected by the connecting rods 0 with the vertically slidingsleeves G, mounted on the standards C of which one is provided at eachend of the machine. Said sleeves G are each provided on the rear sidewith a pocket, C closed by asuitable plate, and through said pockets 0"the needlecarrierD is passed to slide in the direction of its length andin the horizontal plane.

On one end of the bar D the downwardlyprojecting arm D is fastened,which is mounted to slide vertieall y in a guidegroove of a standard, D-formed on the end of the fiat bar D which is mounted to reciprocatehorizontally in the direction ofits length, an d is provided at itsfront edge with a pin and roller, D, which latter is passed into acam-groove, D, in the rim of a cam-pulley, D, mounted on the pivot E,projecting from the side of the frame A, said pulley D being madeintegral or firmly connected with a cog-whcel, E, of the same diameter,with the teeth of which cogwheel the dog can engage, pivoted on theupper edge of the rocking lever E provided on its lower end with aroller, E, resting on the rim of the cam-wheel Ff, mounted rigidly onone end of the shaft E, journaled in suitable brackets in the front partof the frame A, and provided at the opposite end with an arm, Econnected by a connecting-bar, E

with the side of the cam-wheel A mounted rigidly on that end of theshaft A opposite the one on which the wheel or disk B is mounted,whereby the shaft E is rocked from the main driving-shaft A. Springs areprovided for pressing the roller E" against the rim of the cam E andpressing the dog E on the rim of the cog-wheel E. A locking-pawl, Eengaged with the rim of the cog-wheel E, is pivoted above the rim ofsaid wheel and serves to prevent the return movement of the wheel, andalso to prevent said wheel from being moved forward more than one tooth.

The needle-carrier D is provided in its face with a longitudinal groove,F, above which the rib F projects from the face of the needle-carrier,which rib is held on the needle-carrier by means of suitable angle-ironsor other suitable fastening devices. In the bottom of the groove Fnotches or recesses F are formed at suitable intervals, through whichthe needles G can pass. The upper end of each needle is held in aneedle-holder formed of a plate, G, provided with a longitudinal slot, Gthrough which a screw, G, is passed and screwed into an aperturein theneedle-carrier D, said screw serving to hold the needle-holder in placeand prevent it from shifting in the direction of the length of thegroove F.

On the plate Ga clamp, G is held by a screw, G passed through said plateG and screwed into an aperture of the plate G, the said plates G and Gbeing provided in their adjacent faces with grooves for receiving theupper end of the needle. As the plate G is provided with a slot, G theneedle-clamping device can be shifted in the groove F in the directionof the length of the needle-carrier, and can then be locked in place bymeans of the screw G, the screw G serving only to clamp the needle.

The presser-foot H, provided with slots for the needles, is secured tothe lower ends of bars H, passed through guidelugs on the back of theneedle-carrier, and having their upper ends bent over and fastened onthe angle-bar H parallel with and above the needlecarrier, whichangle-bar H rests on cam-arms H of a rock-shaft, H, provided at one endwith an arm, H provided on its lower swinging end with a roller, onwhich the cam projection H on the rim of the wheel B can act.

Springs H are fastened to the bar H and to parts of the frame of themachine and press the foot down upon the bed or throat plate I. From theupper part of a bar, J, fixed on the frame slightly above and in frontof the angleiron H, lugs Jproject, in which check-screws J are held,against which check-screws the angle-iron H strikes when it is raised,thus preventing it from being raised too high, Fig. 7. From the upperedge of the bar J the thread-guides J 3 proj ect,which consist of loopsor rings. Above the bar J a rocking shaft, K, is mounted parallel withthe bar J, and from said rocking shaft K take-up arms K project,provided at their outer ends with eyes, through which the threads arepassed. On each end of the rock-shaft K an arm, K is fixed, having asegmental slot, K. In each slot K a block, K, is held adjustably, andfrom the same a pin, K projects through a slot, L, in the upper end ofan arm, L, pivoted on the top of the corresponding sleeve, 0. Aset-screw, L is held in the upper end of the arm L and projects downinto the slot L from the upper end of the same. As the arm L swingsdownward, the inner end of the pin L strikes the pin K and swings thearm K downward. WVhen the connecting-bar L moves upward, the arm K isswung upward by the spiral springs L secured to pins projecting from theinner end of the arms K and having their lower ends fastened on part ofthe machine-frame. An arm, K and the parts connected therewith areprovided on each end of the rock-shaft K.

The rock-shaft K is provided at each end with an arm, M, projectingtowardthe front, the outer end of which arm can rest against or strikeascrew, M, held in the end of a lever, M, pivoted on the front of abar,M ,fastened on the frame of the machine above and in front of therockshaft. The levers M are pulled downward by the springs M*, securedto said levers and to the .bar J. A lever M and parts connected theretoand an arm M are provided at each end of the rock-shaft K and bar M. 011the front of bar M threadguides are fastened, and above the same thelower ends of the spring-strips N rest on the front of the bar M, theupper ends of the tension-springs N being fastened on the bar N, eachspringNbeing provided with a screw, N, for adjusting its tension. On thetop edge of the bar M the thread-guides N are fast ened.

From the frame of the machine the arms N project, carrying the barsparallel with the needle-carrier, said bars N carrying the pins N,onwhich the spools N are mounted loosely. The spools are arranged in tworows to permit arranging agreaternumber of spools in available space.

The bed or throat plate I of the machine is fastened on the top of theshuttle-guide R, which guide is mounted to slide parallel with theneedle-carrier between the guides O on the top plate, O" ,of the frameof the machine, said shuttleguide being connected with the bar D Belowthe shuttleguide the T-shaped bar P is mounted to slide in the directionof its length and parallel with the needle carrier between theguide-lugs p projecting upward, the bars 1? being mounted to slide belowthe plate 0' at right angles to the T- shaped bar P, said bars I? havingracks P formed at their outer projecting ends on their bottom edges,which racks engage the cog-wheels P, mounted on the shaft E, theconnections for which were previously described, and which is the sameshaft which carries the cam wheel D The bar P can thus reciprocate inthe direction of its length and can be moved by the bars P in adirection at right angles to its length.

On the bar P the shuttle-holders Qare fastened, which carry and hold theshuttles Q, which are of the usual construction, and which each containa bobbin, also of the usual construction.

The several shuttleholders Q on the bar P project upward into thecompartments formed in the shuttleguide R. The bases of theshuttle-holders are provided with the slots Q extending transversely tothelongitudinal axis of the shuttle-holders, through which slots Q,

. the screws Q 'are passed into the upper surends bent over at rightangles, so as to be approximately U-shaped, said bent ends restingagainst the inner sides of the bars R. The cross-bars R" are providedwith the slots 11* (see Fig. 10) in the sides and the slits R andgrooves It in the ends. In the said end grooves, It", ofeaeh cross-pieceR a nut, S, is hcld,which is screwed on a screw, S, in aside piece, R.The screw can be loosened from the outside, and then the cross-pieces Itcan be shifted in the direction of the longitudinal axis of theshuttle-guide, and then locked in place by turning up the screw. Thecross pieces It of the shuttle-guide can thus be ad justcd on the sidepieces, and thus the said cross-pieces It can be adjusted to thepositions of the shnttleholders.

The side bars, R, of the shuttleguidc rest upon crosspieces R", passedunder the bar P and through notches Rf in the bottom edge of the same,said crosspicces It resting on the tracks It of the bed-plate of themachine.

The iced-rollers T T are mounted to revolve on their longitudinal axisbehind the needleearrier, the roller T being journaled in movable boxes,which can be controlled by a screw and spring in the usual manner. Attheir ends the feed'rollcrs are provided with the cogwheels T, engagingwith each other, and on end of the shalt of the roller T the ratchetwheel T is mounted, with which the dog T engages, pivoted on a lever, T,carrying on its free end a roller, T, which travels on the cam U, formedon the edge of the pulley A.

A cog-wheel, V, is mounted on the end of the shalt of the roller Tadjacent to the ratchetwheel T, and with the teeth of the cog-wheel Vthe toothed end of an anglclever, V, can engage, which carries on itsend a roller, V running on a cam, V, mounted on the shaft A and having anotch, V. A curved guardplate, XV, projects downward and toward thefront from the sewing-plate I and covers the D gearing for moving theshuttle-guide.

spring, m is fastened, the lower ends of which are connected with thesliding sleeve 0 for pulling the same upward.

The operation is as follows: The rock-shaft B is operated from thepulley B by means of the connecting-rod B, and from said rockshaft thesleeves G are reciprocated vertically by means of the connecting-linksO. The needle-carrier D, which is mounted to slide horizontally inthesleeves O, is thus reciprocated vertically with said sleeves. Thevertical end pieces, D, on the ends of the needle-can rier D slidevertically in the grooved vertical guides or standards D of the bar Dwhich bar D is reciprocated by the action of the sides of the cam grooveD in the pulley D on the roller D" of the bar D". The pulley D isrotated at regular intervalsby the action of the pawl E on the teeth ofthe ratchetwheel E, connected with the said pulley D, said pawl beingoperated by the rocking lever which in turn is operated by the pulley onthe rocking shaft E. As the racks P are engaged with the cog-wheels P onthe rock-shaft E, said cog-wheels are rocked with the shaft, whereby ahorizontal reciprocating motion is given to the racks P in a directionat right angles to the horizontally-reciprocating motion of the needlecarrier. As the bar P, supported by racks, is between the lugs P on theracks P said bar P is also reciprocated in a horizontal plane in adirection at right angles to the horizontal reciprocating move ment ofthe needle-carrier. The sh uttle-holders Q, which are located in thesubdivisions of the shuttle-guide R, are fastened on the bar P, and arethus reciprocated with the bar P horizontally at right angles to thedirection of reciprocation of the needle-carrier. The shuttle-guide R,resting on the cross-pieces R on the base of the machine, is adapted toreciprocate on the same horizontally in a direc tion parallel with thatof the needlcrarrier,

and is reciprocated in said direction by the action of the cam-groove Din the pulley D on the roller D'*, which is held on a projection of thebar D, with which the shuttleguide is connected as stated. Theshuttle-holders are thus reciprocated on a horizontal plane at rightangles to the direction of the needle by the action of the pulley on therock-shaft E. The shuttle-holders in which the shuttles are held arethus reciprocated horizontally at right angles to the needle-carrier,and also parallel with the needlecarrier. The reciprocations in thedirection at right angles to the needle-carrier take place veryfrequently and rapidly-that is, once in each direction for eachstitch-whereas the reciprocations in the direction parallel with theneedle'carrier take place at greater intervals and are governed by theshape of the cam-groove 1) in the pulley D. The parts are so adjustedthat one reciprocation of the shuttlecarriers in a direction at rightangles to the needle-carrier takes place for each vertical -stroke ofthe sleeves IOC ,ment is necessary, as the needle-carrier isreeiprocated vertically at the same time that it is reciprocated in ahorizontal plane. Whenever the needles are raised and the cloth is to befed forward by the feed mechanism, the operation of which will bedescribed hereinafter, the presser -foot H is raised, which isaccomplished by the arms H on a rockshaft, H, provided with the arm H,which in turn is operated by the cam H on the pulley B. The take-up armsK, through which the threads are passed, are fixed in the rocking shaftK,which is operated by the connecting-bars L from the vertically-slidingsleeve 0. The distance that the take-up arms travel can be regulated byadjusting the blocks in the slots K of the arms K a greater or lessdistance from the shaft K. The springs M serve to counterbalance thepresser-foot. The levers M are swung up immediately after the stitchesare locked,and thus give slack thread to-permit the needle-carrier andshuttle-guide to be moved longitudinally, both of these membersbeginning to movein the direction of their length as soon as the leversM start, whereby all side pull on the fabric is prevented. Thefeed-rollers are operated by the action of the pawl T* of the arm T onthe ratchet-whee1T which arm T is operated by the cam V on the pulley AThe wheel V on the same feedroller with the ratchet-wheel T is locked inplace during the time that the pawl T does not operate on theratchet-wheel, which is operated by the cam V acting on the roller onthe outer end of the arm V, the toothed end of the cam engaging with theteeth of the cogwheel V. The cloth or fabric is moved through themachinein the direction ofthe arrows a a Fig. 7, and is represented bythe letters, Fig. 7, and passes over the guide, as indicated by thearrows a", Fig. 7.

During the passage of the fabric through the machine a row of stitches,t, is formed, as shown in Figs. 17 and 19, the formation of thesestitches being governed by the shape of the cam-groove D in the pulleyD, as said cam-groove shifts the needle-carrier and shuttleguide in ahorizontal plane gradually. After the fabric has passed entirely throughthe machine the fabric is passed through again, but is so adjusted thatthe second row of stitches crosses the first row, thus producing thedecloser together while making the second rows of stitches than whenmaking the first, as the cloth shrinks more or less during the time thatthe first row of stitches is being made. i

The plates G, in which the needles are held, can be shifted after thescrews G3 have been loosened. The cross-bars R of the shuttleguide canbe adjusted after the-screws S have been loosened, and theshuttle-holders Q can be shifted on the barP to correspond with theadjustment of the bars B after the screws Q have been loosened. Theshuttles and needles used are of the usual construction. The shuttlesand needles can be removed and replaced very easily and rapidly.

So that the operation of the machine will be fully understood I willrecapitulate. The needle-carrier is reciprocated vertically and theshuttles are reciprocated horizontally at right angles to theneedle-carrier for each stitch. For each stitch the take-up arms K arerocked once, as are also the rock'shafts B and E. The needle-carrier andthe shuttleguide, and also the shuttle-holders, are reciprocated inhorizontal planes parallel with the needle-carrier. During the time thatthe needles are raised the feed-rollers T T are rotated and the cloth orfabric moved in the direction of the arrows a a while during the timethat the needles are passing down and up through the fabric thefeed-rollers are locked in place by the mechanism described.
